ISIS jihadists laughing and joking while a slave girl is heard screaming

Harrowing footage from a dead terrorist's phone appears to show ISIS fighters laughing and joking while a woman can be heard being raped in the background.
One suspected ISIS fighter sits in the middle of the floor playing with his friend's underwear and sipping from a small glass in what appears to be a living room.
Two far affiliates sit on a large sofa laughing at the seated man as he gestures with the clothing and a fourth man can be seen milling around in the room.

All the while, a woman can be heard wailing nearby, but the pictures are not picked up on video.
Speaking in an Iraqi accent, the man sitting on the floor says: 'I went to Abu Aziz when he shouting for his slave and I stole his clothes - now I came here and now he has no clothes.
'I arrested his clothes (joke).
'Now I'll let him go out of the house naked with no clothes. This video is for my love Abu Aziz.'

His fat friends sat on the sofa say, 'don't film, don't film', while laughing.
The video was captured on the phone of a dead ISIS terrorist, according to Radio Sawa, who say the clothes belong to the seated man's friend who is carrying out the rape.
As well as the distressing screams of the woman, commands can be heard coming from a walkie-talkie which is sat on the floor next to the terrorist who is sat cross-legged on the floor with a tray in front of him.
It is understood the slayed terrorist died in Shirqat near Mosul, Iraq.
